Abstract
Yan, Z., Bai, M. & Ren, D., 2012. A new genus and species of fossil Hybosoridae (Coleoptera: Scarabaeoidea) from the Early Cretaceous Yixian Formation of Liaoning, China. Alcheringa, 1–7. ISSN 0311-5518.
A new genus and species of a well-preserved fossil hybosorine (Coleoptera: Scarabaeoidea: Hybosoridae), Fortishybosorus ericeusicus Yan, Bai & Ren, is described and illustrated from the Early Cretaceous Yixian Formation of Huangbanjigou, Liaoning Province, China. The new fossil can be differentiated from all other hybosorines by its large and strong mandibles, two spurs of different length on the end of the metatibia, three teeth on the outer margin of the protibia, short and robust legs, no striae or tubercles on the elytra, and two well-developed wings. This is the first record of hybosorids from the Early Cretaceous Yixian Formation of Huangbanjigou, Liaoning Province, China.
采自中国辽宁省黄半脊沟早白垩世义县组的保存良好的化石hybosorine(Coleoptera: Scarabaeoidea: Hybosoridae) 在此得以描述并图示。新化石与其它同类化石的区别在于, 它具有大而粗壮的下颚, 后胫骨末端有两个长度不一的距, 前胫骨外缘有三个齿, 腿短而壮实, 鞘翅上无纹路或小瘤突, 翅发育良好。这是该地早白垩世义县组内hybosorid的首次记录。
